Fixed bug 1587 - "aclocal" fails to generate a sufficient "aclocal.m4"

Cecil Curry 2012-08-27 16:55:12 PDT

Allow "aclocal" to find the "AC_CHECK_DEFINE" macro.

On running:

rm aclocal.m4
libtoolize --install --copy --force
aclocal -I acinclude
autoconf -I acinclude

The former three commands succeed, but "autoconf" fails with: error: possibly undefined macro: AC_CHECK_DEFINE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.

"aclocal" fails to find AC_CHECK_DEFINE and hence add such macro to
"aclocal.m4". Here is why:

* "acinclude/ac_check_define.m4" defines AC_CHECK_DEFINE via define() rather
than AC_DEFUN().
* "aclocal" fails to find macros defined via define().
     1 The latest development version of SDL is available via Mercurial.
     2 Mercurial allows you to get up-to-the-minute fixes and enhancements;
     3 as a developer works on a source tree, you can use "hg" to mirror that
     4 source tree instead of waiting for an official release. Please look
     5 at the Mercurial website ( ) for more
     6 information on using hg, where you can also download software for
     7 Mac OS X, Windows, and Unix systems.
     9   hg clone
    11 If you are building SDL with an IDE, you will need to copy the file
    12 include/SDL_config.h.default to include/SDL_config.h before building.
    14 If you are building SDL via configure, you will need to run
    15 before running configure.

    21 There is an RSS feed available at that URL, for those that want to
